STATISTICS AND RESEARCH METHODS 2
1. We hypothesize that the students’ intention to volunteer increases after the service-learning project.
2. We hypothesize that females have more intention to volunteer compared to males after the service-learning project.
Hypothesis 1 was tested using a Wilcoxon signed rank test as the data was ordinal and therefore violated the condition for a t-dependent test. Hypothesis 2 was tested using a Mann-Whitney U test as the data was also ordinal and did not meet the assumptions of scale or interval data for a t-independent test.
Results
A Wilcoxon signed rank test indicated that there was no significant difference in students’ intentions for volunteering before and after service-learning (SL), T =140.00, z = -1.189 (corrected for ties), N – Ties = 27, p = .235, two-tailed.
Overall, 8 participants had lower intentions to volunteer after SL (sum of ranks = 140.00), 13 participants had no change in their intentions and 13 students had increased volunteering intentions after SL (sum of ranks =238.00).

A Mann-Whitney U test indicated that there was no difference in male students’ intentions to volunteer (Mean Rank = 25.08, n = 6) compared to female students (Mean Rank = 19.69, n = 34), U = 74.50, z = -1.073 (corrected for ties), p = .283, two-tailed. This is illustrated in Figure 1.

Discussion
The results indicated that both hypothesises were null. Many students experienced no change or insignificant changes in their intentions to volunteer before and after SL. For the second hypothesis, conversely, a larger number of male participants than female participants actually had stronger intentions to volunteer after SL, as shown in Figure 1. This matches up with my personal experiences. For the first hypothesis, I rarely found that I felt more interested or motivated to volunteer after volunteering. This might be because people are often motivated to volunteer by intrinsic motivations compared to situational influences (Porter, 2017). I personally feel that I was just as likely to volunteer before and after a volunteer session, also possibly because my schedule was a big factor in when and whether I scheduled volunteering sessions for myself. For the second hypothesis, I agree with the results as I do not think that my male coursemates are more selfish and less willing to volunteer up their time to help others. Often, I notice that many of them are just as enthusiastic about volunteering as the female students and consider volunteering to be a meaningful way to spend their time. Additionally, I myself have volunteered multiple times with different male classmates. The results thus match up with my personal experiences.
This implies that future mandatory volunteering or community service projects for students may not be a method to promote volunteering attitudes among students, as they had no effect on their intentions. In addition, it also means that SL and volunteering events do not have to specifically target male students to encourage participation, as there is already equal participation and volunteering intentions across the sexes.
A notable limitation of this study is that there were only a handful of male participants, so results are likely not representative of male students in general. In addition, the students surveyed were psychology students and, so volunteering is a key part of increasing their employability (Bromnick, Horowitz & Sherpherd, 2012; Twomey & Byrne, 2011). They therefore likely already had intentions to volunteer prior to the SL. Possible directions for future research could then be surveying humanities students to understand if such students do indeed volunteer more and generally feel more positively towards volunteering compared to other students.
